NOW COMPATIBLE WITH TI-89 AND TI-92+. The best program for TI calculators that trace frequency plot of a transfer function W(s) - Bode plots -. BodeX has full semilog grid and use a powered routine to plot the phase plot of a transfer function (don't use simply the angle() function). The BodeX routines ensure the correct phase plot any W(s) it's plotted. What's new in version 2.0.5: now you can plot MAG plot and Phase plot in Split Screen Mode or plot MAG and Phase separately and a bug of BodeX ver.1.3 fixed, and powered routine for semilog grid
